APEX 2013: The inclusion of Petey Pirahna?

Apparently during the 2013 APEX livestream of Smash Bros Crusade: Petey Pirahna actually made it into the game with actual Gameplay footage. However, Petey was never included in the finalized roster

Now this isn't a butthurt or a rage topic of mines but I'd like to ask why such inclusion was made when it was never confirmed in the first place? Also, wouldn't creating new characters like this slow down the progress on getting the full roster done because there's no direct focus on it then?

I really have nothing to argue here but it did caught me off-guard so feel free to discuss the inclusion of Petey Pirahna in SSBC and whether or not you feel okay with having him in the roster now
